In lighting design, the performance of daytime and night effects is very important. In order to show more vivid landscape effect at night, it is necessary to design lawn lamp lighting system scientifically and reasonably.
(1) Firstly, determine the style of lawn lamp.
For example, the transmittance of the luminous cover of lamps is 100% full transmittance or 50% semi-transparency of frosted sand. This value can easily be ignored, but it will affect the average road illumination Eav after the completion of the project.
Then determine the height of lawn lamp (generally in the range of 0.4-0.8m), the specific height is calculated according to the type of lamp selection and the spatial proportion of different project models.
(2) After the basic conditions have been determined, point placement will be started.
The arrangement is divided into three kinds of "zi", "unilateral" and "bilateral".
The distance between lamps and lanterns should be calculated according to the width of road surface and the illumination required by the specifications. For example, the word "lawn lamp with height of 0.45m" is used with a width of 2m. In order to ensure that the specifications require Eav=10-15lm/, the distance between lamps and lanterns should be controlled between 8-12m.
According to the characteristics of the project and the location of the beautiful and symmetrical arrangement, it ensures that each entrance has a set of lawn lamps, which not only meets the illumination, but also plays a prompting and guiding role. Increasing distance will inevitably lead to an increase in illumination. However, according to the existing conditions, the illumination of the single light source can be calculated to reduce to meet the average control illumination at the beginning of the design. Degree.
(1) Unilateral arrangement
This method is suitable for straight-line pedestrian roads, which are arranged on the right side of the road (according to the rules of the road). It is more economical because it saves crossing pipelines and cables between roads.

(2) Bilateral arrangement
This kind of method is less used in practical projects, mainly according to the European axisymmetric characteristics of highlighting the sense of ceremony, using special sector light surface to enhance lighting effect, but not in conventional lighting, because of its low economy, it will increase the amount of pipelines, cables, lamps and lanterns.

(3) Layout of words
This method is suitable for curved roads. Over-use of one-sided arc layout will lead to uneven illumination, and the use of zigzag layout can better solve this kind of problem.
